How to Make Soil Less Acidic for a Healthier Monstera

by

Monsteras are popular houseplants known for their large, striking leaves. To keep them healthy, it’s important to maintain the right soil pH. If your Monstera’s soil is too acidic, it can hinder nutrient absorption and stunt growth. Fortunately, there are simple ways to make soil less acidic and promote a healthier plant.

Understanding Soil pH and Monsteras

Soil pH measures how acidic or alkaline the soil is, on a scale from 0 to 14. A pH of 7 is neutral. Monsteras prefer slightly acidic to neutral soil, ideally between 5.5 and 7.0. When soil pH drops below this range, it becomes too acidic, affecting nutrient availability and overall plant health.

Signs of Too-High Soil Acidity

Indicators that your Monstera’s soil may be too acidic include:

  • Yellowing leaves
  • Stunted growth
  • Root rot or decay
  • Poor overall vigor

How to Reduce Soil Acidity

There are several effective methods to raise soil pH and reduce acidity:

Add Lime

Applying garden lime (calcium carbonate) is one of the most common ways to neutralize acidity. Mix a small amount into the soil around your Monstera according to package instructions. Recheck pH after a few weeks and repeat if necessary.

Use Dolomitic Lime

Dolomitic lime contains magnesium along with calcium, which benefits your plant. It acts faster than regular lime and provides essential nutrients while reducing soil acidity.

Add Wood Ashes

Wood ashes from hardwoods can also raise soil pH. Sprinkle a thin layer into the soil and mix well. Use sparingly to avoid over-alkalizing the soil.

Additional Tips for Healthy Soil

Besides adding amendments, consider these practices to maintain optimal soil pH:

  • Test soil pH regularly with a reliable kit
  • Avoid overwatering, which can increase soil acidity
  • Use well-draining soil to prevent root rot
  • Apply organic compost to improve soil health

Conclusion

Adjusting soil pH is a crucial step in caring for a healthy Monstera. By monitoring soil conditions and using natural amendments like lime or wood ashes, you can create an environment that supports vibrant growth. Regular testing and proper soil management will ensure your Monstera thrives for years to come.
